Lisle data center faces renewed scrutiny over diesel generators, ongoing construction
CSquare's data center in Lisle faces renewed scrutiny from residents and the Village of Lisle over the use of diesel generators and ongoing construction. Residents complain about noise, smell, and smoke, while the village questions permitting for temporary generators and the overall scope of modernization work. A DuPage County judge previously ordered a halt to exterior work earlier this year due to permit issues.
The CSquare data center in Lisle is once again under scrutiny following complaints from neighboring residents regarding the operation of several diesel generators and ongoing construction work. Residents reported noise, unpleasant smells, and black smoke emanating from the facility.
Catherine Smith, Chief Administrative Officer for CSquare, stated that the company is currently operating one diesel generator under a temporary village permit and possesses nine permitted permanent back-up generators. CSquare is also seeking permits for four additional temporary generators necessary for critical workloads, asserting that the ongoing work focuses on modernizing electrical, cooling, and mechanical systems to meet safety standards and minimize environmental impact. The company has initiated a door-to-door campaign to inform residents.
Earlier this year, the Village of Lisle ordered CSquare to cease construction work for a fuel cell installation due to a lack of proper permits, leading to a court case. In late February, a DuPage County judge issued an order halting exterior work but allowing interior work with appropriate permits, and permitted a temporary chilling system to remain. Following the recent complaints about diesel generators, Lisle Development Services Director Mike Smetana requested CSquare stop using temporary generators, and both parties met to discuss the situation. Smetana believes most temporary generators are no longer in use, with confirmation pending.
The village seeks a comprehensive understanding of the data center's operations and power needs, with Village President Mary Jo Mullen emphasizing the need for CSquare to provide a full scope of its planned activities. Both sides are scheduled to return to court on August 17 for an update on the initial February court order, where the village expects to address any new concerns.
